4. Equipment Features

1. Low failure rate and fast changeover (auto-adjustable filling pump reduces tuning time; optimized fixtures—only two screws to switch model).

2. Easy routine maintenance and quick PTFE (Teflon) tape replacement; higher productivity.

3. One-to-four ceramic metering pump with high accuracy; set fill mass on the HMI; greatly shortens tuning/changeover; anti-jam pump design.

4. Fixture 1-out-2 working mode; supports atmospheric fillingvacuum degassingvacuum sealing.

5. All chambers use mechanical mechanisms for actuation—simplifies structural/electrical/pneumatic layout maintenance and speeds troubleshooting.

6. Dedicated electrolyte tank supports vacuum degassing in-tank, greatly reducing bubbles and contamination of the vacuum system.

7. Pneumatic components, electrical parts, and the electrical cabinet are isolated to avoid electrolyte contamination.

8. Adaptable to various cell sizes; simple adjustments—mainly fixture and fill mass.

9. Left/right sealing heads are cylinder-driven and guided by linear rails; smooth travel, accurate guidance, and flat seals.

10. Sealing heads made of copper for excellent heat transfer.

11. Left/right sealing-head pressure adjustable via regulators to meet different process requirements.

12. Left/right sealing-head temperature set on the temperature controller; PV/SV values displayed for intuitive operation.

13. Alarms for temperature abnormality, air-pressure abnormality, reset, etc.; machine only runs after reaching set temperature & pressurebuzzer prompt.

14. Pressure gauges with digital display and manual regulators for easy pressure setting.

15. Auto / semi-auto / manual modes; interlocked memory between auto and semi-auto.

16. EPDM sealing strips used for vacuum seals to resist electrolyte and extend life.

17. Swivel casters on lower frame for easy relocation.

18. For quality, all vent-in air for vacuum-chamber backfill must be dry gas from the machine.

19. Due to the complexity of pump control and machine control, an independent electrical cabinet is designed for easy maintenance.

20. Belt-type loading reduces labor, raises efficiency, and lightens operator workload.

 

5. System Protection Functions

1. Temperature controller provides over-temperature alarm to protect machine and cells.

2. Whether in auto or manual, all units with precedence logic are reliably interlocked to prevent mis-operation and hazards.

3. Anti-mis-step foot switch prevents unintended actuation.

 

6. Equipment Functions and Operating Process

1. Supports the following sequence: Manual loading → Automatic filling → Automatic degassing → Automatic vacuum sealing → Manual unloading.

2. Electric pump connects automatically via an intermediate electrolyte buffer tank to two electrolyte tanks (with newly added degassing function).
